The D4-S is going to scare a lot of traditional Subie 'tuners' and they may go EJ and start off with claiming the EJ is better, blah, blah... But once a couple serious guys get a hold of an FA and figure out what they're doing and what it's capable of, it'll likely surpass the EJ.

Scared, no way! I love change and I love the opportunity to make big power on this new engine. Both NA and turbo! We heard that Cosworth is already in the works for both NA and turbo power!

Good point for sure. The deal breaker could be that you need a standalone ECU to run the EJ. Or if an the EJ engine works, I bet customers would need to buy a 2008+ STI ECU/engine to ensure the dash and traction control/DSC stuff still functions. This all adds up quick, and may mean that its not as common as we think it might be. There are quite a few unknowns at this point we will just have to see.

The 2012 civic has a 2.4L too though, so even though it makes the same HP at the same peak RPM, it doesn't have GDI so the output per displacement is not the same. The older K20 made 200HP at closer to 8k RPM.

Good point! The FA makes 200HP at a lower RPM than the K20. So does that mean there is a ton left on the table for those who want to rev to 8500 (with proper mods)? I say yes!
The K20 engines make great HP with a few goodies. I have seen 220WHP from them, which is outstanding! Even a few 250 WHP cars with cams and 9000RPM.
